Process for the partial oxidation of a liquid or solid and/or a gaseous fuel using a multi-orifice burner comprising a central channel and four concentric channels encircling the central channel. Liquid or solid fuel is supplied through the second concentric channel and the oxidizer is supplied through the first concentric channel and the third concentric channel. Hydrocarbon gas and/or moderator is supplied through the central channel and the fourth concentric channel. The mass ratio of liquid or solid fuel to hydrocarbon gas ranges from 0 to 1.

Process for partial oxidation of a liquid or solid and/or a gaseous

A protruding mantle separates burner internals from the hot gasification environment. The mantle is cooled by at least one of the feedstreams. The lining can be made of ceramics such as silicon carbide and/or silicon nitride. In order to lower thermo-mechanical stress the lining is thin-walled.

Ceramic burner for partial oxidation of a hydrocarbon-containing fuel

Process for the partial oxidation of fuel using a multi-orifice burner comprising a central channel and three substantially concentric channels encirling the central channel. Fuel is supplied through each of the first and third concentric channels and the oxidizer is supplied through each of the central channel and the second concentric channel. The reactant fuel and oxidizer are supplied at specific mass flow distribution and velocities.

Process for partial oxidation of a hydrocarbon-containing fuel

A process for the partial oxidation of fuel using a multi-orifice burner comprising a central channel, and three concentric channels encircling the central channel, is disclosed, fuel being supplied through the second concentric channel at a specific velocity and oxygen being supplied through the other channels at specific mass flow distribution and velocities.
